[SCSI] libiscsi, iscsi_tcp: iscsi pool cleanup
iscsi_pool_init simplified
iscsi_pool_init currently has a lot of duplicate kfree() calls it does
when some allocation fails. This patch simplifies the code a little by
using iscsi_pool_free to tear down the pool in case of an error.
iscsi_pool_init also returns a copy of the item array to the caller.
Not all callers use this array, so we make it optional.
Instead of allocating a second array and return that, allocate just one
array, of twice the size.
Update users of iscsi_pool_{init,free}
This patch drops the (now useless) second argument to
iscsi_pool_free, and updates all callers.
It also removes the ctask->r2ts array, which was never
used anyway. Since the items argument to iscsi_pool_init
is now optional, we can pass NULL instead.
